# How to use Phyllome OS
|
|
|
|
*This section explains how to further configure Phyllome OS, and how to deploy a tiny and live operating system within it.*
|
|
|
|
## Post-installation configuration
|
|
|
|
After Phyllome OS [has been successfully installed](/deploy/install) and [its first-launch process completed](/deploy/install#first-launch), a few tasks are required before it can be used to its fullest potential.
|
|
|
|
> As Phyllome OS evolves, one of the main goal is to shorten the time it would take for an end-user to have a fully operational virtual machine loaded with the installer of their favorite operating system, to the point that a user may not see the Phyllome OS environment
|
|
at all.
|
|
{.is-info}
|
|
|
|
> The following post-installation configuration will, hopefully, be made obsolete in a future Phyllome OS version.
|
|
{.is-info}
|
|
|
|
### Grant the current user the ability to manage virtual machines
|
|
|
|
Any new user, including the one that has been created during the first-launch set up, won't be part of the `libvirt` group. It means that it won't be able to manage the *qemu:///system*, which runs `libvirt` as root.
|
|
|
|
To avoid a password prompt each time the Virtual Machine Manager is launched, you can add the current user to the `libvirt` by using the following command, in the terminal:
|
|
|
|
```
|
|
sudo usermod -a -G libvirt $(whoami)
|
|
```
|
|
> A known bug affects the terminal: extra spaces between letters. To solve it, click on the burger menu (the three stacked horizontal lines) then go to *Preferences > Profiles > Unnamed* and check the box called *Custom font*.
|
|
{.is-warning}
|
|
|
|
> Phyllome OS will eventually switch to the *qemu:///session* URI, which doesn't require elevated privileges. Have a look at [this great blog post](https://blog.wikichoon.com/2016/01/qemusystem-vs-qemusession.html) to understand some of the differences between the *session* and the *system* URI.
|
|
{.is-info}
|
|
|
|
### Run a few scripts
|
|
|
|
During the installation process, [a few scripts are fetched](https://github.com/PhyllomeOS/phyllomeos/tree/main/post) and stored under the `/usr/sbin` directory. They need to be run to further customize Phyllome OS.
|
|
|
|
#### Desktop enhancements
|
|
|
|
The following script will change the desktop background and pick opinionated defaults for the Virtual Machine Manager. It will also add a new User session URI for the Virtual Machine Manager.
|
|
|
|
Open the terminal and run the following script as a regular user:
|
|
|
|
```
|
|
/usr/sbin/configure-vmm-and-desktop.sh
|
|
```
|
|
*The updated desktop background. Notice that there is now a new URI called QEMU/KVM User session*
|
|
|
|
|
|
|
|
#### Create and run a virtual machine without any attached disk
|
|
|
|
The following script, which also doesn't require root privileges, will create a virtual machine called `my-first-live-vm`. This virtual machine will be started automatically and added to `virt-manager`.
|
|
|
|
```
|
|
/usr/sbin/create-live-vm.sh
|
|
```
|
|
*Notice the new icon under QEMU/KVM: this is the new virtual machine that has just been created. Go to the section to learn how to interact with it.*
|
|
|
|
|
|
|
|
## Access your virtual machine display
|
|
|
|
* Double-click on *my-first-live-vm* to open its virtual display, then click on *Connect to console*.
|
|
|
|
|
|
|
|
> Phyllome OS ships with a small ISO crafted by the team behind [netboot.xyz](https://netboot.xyz/), and that can do network boot, allowing it to do network-based installations of the most popular Linux distributions, among other niceties.

|
* After a few seconds, you will be greeted by the following screen.
|
|
|
|
|
|
|
|
* Under the menu, go to *View* and select *Full Screen*
|
|
|
|
|
|
|
|
* Go to *Live CDs*
|
|
|
|
> There is no disk attached to this virtual machine. As a result, only Live CDs will work out-the-box.

|
|
|

|
|
|
|
* Scroll down this list
|
|
|
|
|
|
|
|
* Stop at *Tiny Core Linux* and press <kbd>Enter</kbd>
|
|
|
|
|
|
|
|
* Select *Tiny Core Linux x86_64*
|
|
|
|
|
|
|
|
* Select *Tiny Core Linux CorePure*
|
|
|
|
|
|
|
|
* Enjoy your disposable virtual machine
|

|
When you are done messing around, input the following, and you will be back in Phyllome OS
|
|
|
|
```
|
|
sudo poweroff
|
|
```
|
|
|
|
> That's it, congratulations!
|
|
